This chicken has been acting very strange. At first she was behind a straw bale. she was there for more than a week... my sisterinlaw said maybe she was broody... I waited and waited and finally I had to move the bale. she flew out!.. and no egg or nothing... I felt bad.. thinking she must of been stuck.. but no.. she did another strange thing... she kept sitting on the nest and wouldn't move. she is not violent or not doing anything other than not wanting to be with the others.. now today I go out and I was missing a chicken.. it was her!! she couldn't of gotten out so she must be there... so I looked everywhere... she is in a small confined space between the wall and cement board.. Do I remove her from there? I do not know what to do? Do chickens do this behavior when they are broody? and what do you do? Do they do anything if they feel they are sick iin anyway and remove themselves from the group? I am so confused.
